The first call came in at 11:29 a.m. Saturday, a minute after Asiana Flight 214 struck the soundwall and crashed at San Francisco International Airport.

"Hi, I'm reporting an airplane crash at ah, SFO," says the man, who identifies himself as Jared Foster. "Yeah, we were hiking on a trail outside of Pacifica, and we just heard a giant explosion with a couple of other hikers, and they saw that an airplane had crashed right there at SFO."

As the dispatcher transfers him to airport authorities, a woman's voice can be heard in the background: "Where the hell's the fire engines?"

The California Highway Patrol on Wednesday released recordings of 911 calls received between 11:29 and 11:56 a.m. on the sunny holiday weekend morning.

The first caller recorded is calm, as is the second, a man who was on the flight. He says there are a "bunch of fire trucks and ambulances" and tells dispatchers that he believes everyone is off the airplane.

Later, however, the tone becomes frantic. One is from a woman trying to tend to a female victim who she says appears to be in her mid 20s. They are not with the broken fuselage of the Boeing 777, but farther down the tarmac closer to where the plane initially hit the ground.

"There is a woman out here on the ... runway who is pretty much burned very severely on the head, and we don't know what to do. ... She is severely burned, and she will probably die soon if we don't get any help."

As the dispatcher reassures the woman that they are sending more ambulances and asks for a specific location, the woman reiterates she fears the victim will die, and she doesn't know what to do.

"Is there any way we can help in any way?" she pleads.

Another caller says they have been on the tarmac for at least 20 minutes and pleads for medical attention.

"We've been on the ground for 20 minutes to a half-hour," says the woman, who identifies herself as Cindy Stone. "We're almost losing a woman here, we're trying to keep her alive."

Cindy Stone's son, Scotts Valley resident Elliot Stone, said earlier this week that he and his family were the first to find the four victims who fell out of the plane immediately after it struck the soundwall.

He said they had gone looking for victims after the crash, and when they peered down the path of wreckage left by the airplane they spotted a woman, covered in blood, stumbling toward them and calling for help. He said she was about 500 yards away.

As they rushed toward the woman, they saw three more still in the wreckage at the end of the runway. Family members split up to stay with each of the injured women while they awaited medical aid.

"We've been on the ground and have not seen one ambulance the whole time," Cindy Stone says in the recording. "No ambulances on site for this plane crash. Lots of fire engines in the distance; not one ambulance out here on the tarmac."
